Description

The XENONnT dark matter experiment aims for the direct detection of weakly-interacting dark matter particles (WIMPs) with an order of magnitude higher sensitivity than its predecessor, XENON1T. By utilising the existing infrastructure of the XENON1T experiment, currently in commissioning at the Laboratori Nazionali del Gran Sasso (LNGS), an upgrade to a multi-ton scale detector can be rapidly realised. The new detector consists of a dual-phase (liquid/gas) time-projection chamber with double the liquid xenon mass and ~35% larger photosensor coverage than the current generation. The upgrade significantly minimises material-induced backgrounds, with internal backgrounds residing at the level of astrophysical neutrinos. This improvement allows for higher statistics of an initial XENON1T WIMP signal as well as the possibility to probe other physics channels with better sensitivity. This presentation will describe the design, preparation, and expected physics reach of the XENON program at the multi-ton scale.
